Full Refund of Premuims paid due to incorrect or no information provided by ALLLIFE

My mom is now 63 years old, a policy was taken out 5 years ago. In December we recieved a letter stating that she needs to go for blood tests. so we called Alllife and said we wanted a full refund of all premuims paid over the last 5 years and for a manager to call us back. All life then cancels the policy without any notice and no call from any manager to address my concerns. I find it absolutelly ludicras that they have been debiting my account for over 5 years and now all of a suddden want to carry out blood tests. Then to make matters worse policy has been cancelled with no feedback on my premiums paid. I then tried to call Alllife and waited on the line for over half an hour as their phone lines are all messed up. I will be taking this up with the ombudsman as this ****************.
